I know Database.Connection in flexscript is how to work, but in the C++ SDK I don't know how to implement the DatabaseConnector.
in flexscript like this
Database.Connection con = Database.Connection("DatabaseConnector");//<<The connection string is my problem
con.connect();
but in C++ SDK? I try to stay in the same form, but it didn't work.
FlexSim::Database::Connection con;
con= FlexSim::Database::Connection("DatabaseConnector");//<<The connection string is my problem
con.connect();
Hi @Sheldon C4, was one of Matthew Gillespie's or Jordan Johnson's answers helpful? If so, please click the "Accept" button at the bottom of the one that best answers your question. Or if you still have questions, add a comment and we'll continue the conversation.
If we haven't heard back from you within 3 business days we'll auto-accept an answer, but you can always unaccept and comment back to reopen your question.
I don't think you can use the Connection constructor like you can in FlexScript and so you probably need to use the connection's static global() method:
Database::Connection* con = Database::Connection::global("DatabaseConnector");
con->connect();
Hi Matthew, I use the global code, but it didn't work.
The error message is "LNK1120 1 unresolved externals".
Thank's for your answer.
It looks like we didn't export that method for modules. Try this code instead:
treenode dbNode = executestring("Database.Connection(\"DatabaseConnection1\")");
if (!dbNode || !isclasstype(dbNode, "DatabaseConnection")) {
// handle the invalid node case
} else {
// This cast is safe because we checked in the if statement
Database::Connection* con = dbNode->objectAs(Database::Connection);
con->connect();
// do other stuff
con->disconnect();
}
I'm sorry late for response this question, but it didn't worked which the method "executestring" return variant type is double, can't cast into treenode.
C++ and FlexScript are quite different. At one time, it was possible to write FlexScript code, and compile it as C++ code, but that isn't true anymore.
Based on the code sample, it looks like your issue is that con should be type FlexSim::Database::Connection*, not FlexSim::Database::Connection. The difference is the * at the end, to indicate that it's a pointer type.
If that isn't the issue, you'll need to clarify what you mean when you say it didn't work. Did you get compiler errors? Linker errors? Or maybe runtime errors? If so, what did the error say? The more specific you are, the better we will be able to assist you.
Jordan, thanks for your reply, the original problem is I don't know how to using the Flexsim's DatabaseConnector in C++ SDK, so I didn't get the error message.
Now I follow the Matthew's answer and trying to connect Flexsim DatabaseConnector,but it didn't work, the error message I wrote in Matthew's comment reply.
